My vote goes to Total Eclipse. It may not be as readily apparent as the other terrible shows mentioned here, but I think that the way the show so disgustingly ruined the potential it showed in the first two episodes makes it so much worse. Plus the cast is just so hateful you WANT to see the BETA rip them apart to stop their incessant bitching. The icing on this curdled cake is how the show has its priorities out of whack. It focuses too much on insipid juvenile "romance" between its disgusting characters rather than the little issue of HORRIFYING ALIENS DESTROYING THE F^&*ING PLANET.

Uh, I'm finished I guess.

Just to clear some things, from my understanding Total Eclipse is based in the VN Muv-Luv's universe (of that it's further based off the Muv-Luv Alternative: Total Eclipse novels which were themselves based off the second plot in the game called Muv-Luv Unlimited and it's sequel Muv-Luv Alternative) which was a adult harem/eroge game. So stuff like the first two episodes won't be a main focus of it probably, considering what it's based on. Then again, I could be partially wrong about that. Blue Gender created by Ryōsuke Takahashi (Armored Trooper VOTOMS, Flag, Gasaraki) is like the first two episodes of Total Eclipse though (and more), you should check that anime out if you already haven't.

After watching Brave 10 my opinion definitely changed, it was by far the worst anime I've seen this year. Main plot was terrible, character development was even worse but expect when trying to squeeze 10 different main characters into a 12 episode series. Also had a pretty ridiculous ending. Only upsides about the anime are the famous voice actors and the fighting scenes.

Unfortunately, 2012 has so many bad anime or disappointing anime (anime that look awesome but ends up wasting its potential).

For me, I'm not too passionate about bad anime because....well....I just think "this is a piece of ()&*^ and it's a waste of time" and I move on. Instead, I sometimes get really pissed on anime that seems so very awesome in the first few episodes and then you slowly watch the series spiral downwards into the pits of anime disgrace.

Each is entitled to their own opinion, but for me there's bad anime and then there's horrible anime. Here's my list of 2012 bad / disappointing anime:

Anime that should've never been created: Saint Seiya Omega (one of the worst in 2012)Brave 10 (after finishing the series, I wanted the time I spent watching this anime back. This series was pointless.)

Disappointing anime that will never live up to their predecessors:Total Eclipse (For a series with such good CG, the characters are simply dull)Sword Art Online (Liked the first few episodes but then it started to seem like an inferior knock-off of the .hack//sign, 1/2 prince or the other "trapped in an RPG game" anime. I'm still keeping my eye out on this series, but so far none of the current episodes have changed my mind.)Aquarion Evolution (Aquarion was.....ok, not great or very bad, but ok. I think only very good anime DESERVE sequels, but nowadays it seems as if "we have no new ideas, so let's do a sequel of anything and everything we can". Yes I'm also talking to you, Hollywood.)

I haven't come across any anime this year that I would consider really terrible, but Sankarea and Black Rock Shooter were somewhat disappointing. I give them 6/10. They both started out pretty good, though.

Natsuyuki Rendezvous (yeah come at me) I'm still watching it, but only to see the ending, no clue how people like any of the main characters

I agree about Natsuyuki Rendezvous. It started off strong but the last three episodes have been way too slow...hopefully it gets better on the next episode...and from what I hear...there are only two episodes left. :/

La Storia della Arcana Famigla - watched it purposefully to give me perspective on the good anime I'm watching and it is doing the trick.

Phi Brain - (I think the first season started in 2011 but ended in 2012 so I'm counting it) take average shounen plot - throw in puzzles that seem complex but are never shown that way - add code-names of actual smart people and presto-chango you get a crappy anime.
